AUTOMAT IC FEEDING MECHANiSM.

SPECIFICATION forming part of Letters Patent No. 367,527, dated August2, 1887.

Application filed May 25, 1887. Serial No. 239,294. (No model.)

T all whom, it may concern:

Be it known that I, GEORGE O. KEENE, a citizen of the United States,residing at Oincinnati, in the county of Hamilton, State of Ohio, haveinvented certain new and useful Improvements in Automatic FeedingMechanisms, of which the following is a specification.

The several features of my invention and I0 the advantages arising fromtheir use, conjointly or otherwise, will be apparent from the followingdescription.

In the accompanying drawi ngs,forming part of this specification, Figure1 is a perspective I5 view of a machine for corrugating sheet metalprovided with my improved feeding mechanism. Fig. 2 is an elevation ofthe right hand end of the machine, as shown in Fig. 1, the end framebeing removed. Fig. 3 is an e1evation of the left=haud end of themachine. Fig. 4 is a view illustrating the means for securing thestriking-pin in the roller.

The device is particularly useful in corrn gatingmachines of the typeshown, but may also be applied to other machines requiring a similarfeed. The rolls A-are suitably mounted in j ournal-boxcs in the sideframes, B. The rolls shown are provided with two sets ofcorrngating-ridges, one set, a, being fine,

the other set, a, being coarse. There are usually blanhs a? between thetwo sets of corrugating-ridges.

The stationary table D is supportedin front of the rolls in any suitablemanner, as by the table E, in such a position as tends to draw bracket0. The sliding table E rests on the the table E away from the rolls. Thesliding table E is preferablyprovided with the gage E.

This arran ement )ermits the )in P to be ad justed with relation to thecenter of the roll.

The mode of operation of the device is as follows: The sheet to becorrugated is placed on table E,against the gage E, its other edgeprojecting beyond the table toward the rolls. 6 The machine is now setin motion, the gearing being so arranged as to turn the rolls in thedirection indicated by the arrows in Fig. 2. When the pin P strikes thearm f of the lever F, the latter is depressed and causes the arm f tothrow the sliding table Etoward the rolls. This movement of the table Ecarries the sheet of metal inward until it is grasped by the rolls andcrimped between them. The mechanism is so adjusted that the sheet isplaced between the rolls just at the beginning of the corrugations. Bychanging the pin P to the other side of the center of the rolls the-sheet of metal is moved forward in time to be crimped by the other setofcorrngations. 8o

\Vhat I claim as new, and desire to secure by Letters Patent, is-

1. The combination of the stationary table D, sliding table E, bentlever F, having short arm f, connected to table E, long arm f, and 8means for operating the bent lever F, substantially as and for thepurposes specified.

2. The combination of the stationary table D, sliding table E, bentlever F, having short arm f, connected to table E, and long arm f, 0 androll A, provided with pin P, substantially as and for the purposesspecified.

3. In a corrugating machine, the combination of rolls A A, provided withcorrugations a a and blanks a table D, sliding table E, arm f, roll A,provided with transverse slot bent lever F, and roll A, provided withada, and pin P, adjustable in said slot all subjustable pin 1,substantially as and for the stantially as and for the purposesspecified.

purposes specified. GEORGE O. KEENE. 5 4. The combination of thestationary table Attest:

D, sliding table E, bent lever F, having short A. L. HERRLINGER,

arm f, connected to sliding table E, and long CHAS. LUDLOW.
